Crater Lake National Park in Oregon is known for having the deepest lake in the U.S., with a depth of 1,943 feet.

Crater Lake National Park, located in southern Oregon, is famous for its stunning blue lake, which is the deepest in the United States. The lake was formed by the collapse of an ancient volcano, Mount Mazama, around 7,700 years ago. Crater Lake has a depth of 1,943 feet (592 meters), making it the ninth-deepest lake in the world. The lake's water is incredibly clear due to its lack of inflowing streams and its high purity. Surrounded by cliffs and mountains, the park offers breathtaking views and is a popular destination for hiking, boat tours, and photography.
